"the Schedule referred to in these Letters Patent and making psrtof the same;

To all whom it may concern.- I r Be it known that I, BENJAMIN I WARREN, of

Fishkill, on the Hudson, in the county of Dutchess' and State of N ewYork, have invented a new-and useful Improvement in (looking-Stoves; and I do hereby declare jthatthe following is a) full, clear,' and exact description thereof, which wi l enable others skilled in theart tomake and usethe same, rei'erence being bad to the accompanying drawing forming' partof this specification.

This invention relates to improvements in cookingstoves, and consists in the application thereto, under an elevated rear, plate, .and] over the oven, in away not to take up any of the space of the stove available forotherfpurposes, of a-magazi rie for holdingfuel, the

bottom of which ishinged orpivote'dat the back part, and shelving downward, and resting, at the front, on a rear elevation of; the grate, andextending the whole length of the same, whereby the fire may be continl uously fed at the back from the magazine, and the latter may have a shaking motion imparted :to'it by i the shaking of the grate. l

Theopening for the supply of the magazine is arranged to coincidewiththe opening through the top for the stove-ware,'and the doors for closing it are ar-' ranged, to form,- when opened, chutes for conducting the coal thereto, and preventing it from being scattered. over the top. '1 a The invention also comprises a castmetalfire-plate for the front and ends,-in substitution of the fire- I brick, whichis madetpossible by the arrangementof a cold-air space betweeri' the shell of the stove and the saidplatc, which leadsthe nce to the bottom of the.

grate, so that the air which protects the plate, and thereby becomes heated, isused to facilitate combustion, which plate opensat the back toward the chute fromthe magazine, and rests on projections of the side walls ofthe chute, arranged to. admit of the a shaking motion of the bottomof the'chute; and v The'invention also comprises an arrangement of the .rear of the grate to rest andwork on friction-rollers,

and the front with a trough, for the better discharge of clinkers, all as hereinafter more fully specified.

Figure 1 is a sectional elevation of my improved stove taken on the line a a; of x fig. 2, and 1 y Figure 2 is a horizontal section of the same taken on the lineg y of fig..1.; Y a a p Similar letters of reference indicate corresponding partsJg A is the magazineor reservoir,placed in the back part of the stove, which is suificiently elevated to pro-, :vide roomfor it above the oven B, and below there- ]movable part 0 of thetop for the stove-ware, and furnish sufilcient descent for the bottom D to insure the sliding of the coal iiito the fire over the back part of l the grate.

The rear. end of the bottom of the magazine is pivoted at E to a bracket, so asto vibrate thereon slightly, y the said vibrationbeing imparted by the shaking of 'the grate on the rear elevated part F, of which the front end of'the bottom D rests.

Theopening through the top of the magazine for thesupply of coal coincides with .theopening through the top of the stove for the ware, so that access may be hadto it by the removal of the parts 0, and by opening the double doors G of the said top, which are so arranged that,"when opened, they will rest-against the walls of the opening in the top, and thereby form chutes, for insuring the passage of the coal'into the magazine.

This magazine is inclosed on all sides, except the H month, which opens to the tire, so that the draught cannot'pass'through it, the same being arranged to pass over it through the space H, and then down un- 'der and above the oven, in the usual-way.

grooves in the sides I along the front and the twoends of the fire-space. It

is made thick and strong, and ribbed on the side next thefire, the better to withstand the action of the heat.

. It is arranged to rest above thegrate and front, and endhorizontal plates, 0, are arranged between it and the shell at the top and bottom, to cause the air, which is admitted at P,-to fiow along against the back to both the ends, where it is caused to pass down under the grate and enter the fire below, so'that the heat.

imparted to it, while cooling the plate, will be restored to the fire, and facilitate the combustion in the same measure that it .is heated above the\temperature of the air that would be admitted directly to'the fire.

The rear part of the grate-is arranged to reston the friction-balls Q, seated in a groove, R, in the oven-' plate, and the front projects under and beyond the bottom of the fire-plate N, and rests on the movable support S, which may be taken out to let the front down for cleaningout.

This arrangement makes it more easy to shake the grate.

The front of the latter is carried downward at U, where it passes under the plate forming a kind of trough, into which the clinkers and other light foul matter may be raked from time to tiine, or caused to fall by the shaking of the grate from the fire for removal or for escape, by the action of the grate, through the passage between the grate and the fire-wall.

This arrangement of the grate for discharging the clinkers and other foul matter through a trough, dipping down under the fire-wall, and rising upward beyond, so as to prevent the escape of coal, except when shaken, is applicable to other stoves, and may be applied to base-burning heating-stoves by elevating the center of the grate, so as to shed the refuse matter toward and over the edges when shaken, or it maybe a plane or horizontal projection of the grate without the trough, or the outer upward projection.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent-- 1. The eombinaiiorv with a cookingstove, of a coalmagazine, arranged be tween the rear top and the oven, and to feed into the fire the whole length of the grate, all substantially as specified.

2. The combination, with a cooking-stove, having the top of the rear elevated, as described, of the magazine, having the bottom inclined into the fire-box, all substantially as specified.

3. The arrangement of the double doors G, opening into the magazine, to rest, when open, against the walls of the opening in the top of the stove, and form mam ghgtes to conduct the coal, all substantially as speci- 4. The inclined movable bottom of the magazine, pivoted at E, and arranged to rest on the rear elevation F of the grate, substantially as specified.

5. The plates I K, joining on the reservoir, forming a chute for guiding the coal into the fire-box, and a support for the fire-plate,-all substantially as specified.

6. The east-iron fire-plate N, arranged to form three sides of the fire-box, and joining on the chute from the magazine, substantially as specified.

7. The arrangement of the air-passage behind the fire-plate, to conduct the air from the register around both ends and down past the terminus of the lower end plates 0 to thegrate, all substantially as specified.

8. Supporting the grate at the rear on the friotion rollers or balls Q, and at the front on the movable holder S, all substantially as specified.

9. The arrangement, in the front of the grate, of the trough U, substantially as specified.

10. The projection of the stove-grate under and beyond the fire-wall, when arranged to provide aspace for the discharge of the debris of the fire, substantially in the manner specified.

The above specification of my invention signed by me this 11th day of January, 187 0.
